The same pattern of an abrupt start of food production dependent on domesticates from elsewhere, and an abrupt and massive population replacement, seems to have repeated itself in many areas in the prehistoric era. In the absence of written records, the evidence of those prehistoric replacements must be sought in the archaeological record or inferred from linguistic evidence.

Explanation and Analysis:

This passage brings up a few important points. First, it talks about how agricultural societies arose in many parts of the world, independently. Diamond has already shown how the environmental qualities of several distinct regions led humans to...

Original

Romeo

(aside) She speaks.
O, speak again, bright angel! For thou art
As glorious to this night, being o’er my head,
As is a winged messenger of heaven
Unto the white, upturnèd, wondering eyes
Of mortals that fall back to gaze on him
When he bestrides the lazy-puffing clouds
And sails upon the bosom of the air.

Juliet

O Romeo, Romeo! Wherefore art though Romeo?
Deny they father and refuse they name.
Or, if thou wilt not, be but sworn my love,
And I’ll no longer be a Capulet.

Modern

Romeo

(to himself) She speaks. Speak again, bright angel! For tonight you are as glorious, there up above me, as a winged messenger of heaven who makes mortals fall onto their backs to gaze up with awestruck eyes as he strides across the lazy clouds and sails through the air.

Juliet

O Romeo, Romeo! Why must you be Romeo? Deny your father and give up your name. Or, if you won’t change your name, just swear your love to me and I’ll give up being a Capulet.
